Does the U800 have a BIOS option to continue boot after a keyboard error?

I have a Corsair K65 keyboard, and I need to switch it back to "BIOS mode" to avoid the B4 error during the U800 boot process. Is it possible to tell the U800 BIOS to continue boot after a keyboard error?

To clarify what I said, the blocking problem during the boot process (error B4) that I described above does _not_ occur if:
1) there is no keyboard connected
2) or, my Corsair keyboard has been manually switched to "BIOS mode"
3) or, my Corsair keyboard is connected to the USB 3.0 ports of the U800 (regardless of the mode)

The solution (3) will be the right workaround for me.
